Patent GB-364003-A (GB)
Title: Improvements in and relating to picture assembling devices for television and picture transmission
IPC: H04N3/08
Filed: 1930-08-21
Abstract: 364,003. Television receivers. TELEHOR AKT.-GES., 156, Kantstrasse, Charlottenburg, Berlin. Aug. 21, 1930, No. 25068. Convention date, Aug. 5. [Class 40 (iii).] In a television system, the image is directly observed as the variations of light of a linear source in a scanning system which comprises a rotating mirror system in which each mirror is associated with a picture strip and the individual mirrors are mounted on members arranged next to one another along the axis of rotation. The surfaces of adjacent mirrors are spaced at equal angles and are parallel to the axis of rotation, whilst the height and width of the mirrors are equal or proportional to the corresponding dimensions of the strips of the picture being transmitted. The scanning device 4 comprises a number of mirror surfaces 4u, 4v .. carried on members 4a, 4b, .. mounted next to each other on a spindle rotated by a phonic wheel 1. The image is viewed directly by the eye 9 as the reflection in the mirrors 4u, 4v .. of the variations in a line glow-discharge tube 5. In order to frame the received image the mirror system is extended to include a number of mirrors greater than that of the picture strips, and to secure phase adjustment the mirror system is then moved axially in either direction. As shown in Fig. 2, the system of mirrors 20 extending over an axial distance 21 is duplicated by a second system of mirrors 22 also mounted on the shaft 25 of a phonic wheel 24. The cylinder of mirrors is formed at one end with an annular track 26 engaged by rollers 27 carried on a forked member 28 formed with a screw-nut 29 engaging a screw-threaded spindle 30, which is rotated to effect axial movement of the mirror cylinder. A mask 23 limits the light falling on the mirrors according to the picture dimensions. Specification 358,411 is referred to. The Specification as open to inspection under Sect. 91 (3) (a), states that a point source of light may be employed, and the mirrors are of dimensions to produce elemental picture portions of a desired area on a receiving screen. Fig. 2 (Cancelled) shows a system in which a plate glow discharge lamp 11 co-operates with the mirror wheel 4 to produce the picture on a screen 8. The system may be formed by grinding a portion of the periphery of a number of plane-parallel glass plates which are cemented together, and by displacing the individual plates relatively to one another after dissolving the cement. The rotary mirror system may be employed for scanning at the transmitter. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in switch handles or similar forms of switch mechanism, particularly adapted for use with portable electrically operated tools such as drills and the like
IPC: B23B45/14
Filed: 1922-09-19
Abstract: 210,113. White, A. E., (Independent Pneumatic Tool Co.). Sept. 19, 1922. Retractive switches; switches, quick-action.-A detachable handle for portable electrically-operated tools, such as drills, contains a double-pole switch for connecting the supply conductors 29 to two contacts 21, 22 which engage contacts on the tool casing when the handle is attached to the tool by screws or like means. The handle comprises two portions 4, 5 adapted to be relatively rotated and then clamped in position by a screw 12 so as to bring a switch-operating trigger 47 into a suitable position. The switch is a snap action one and is adapted when the trigger 47 is moved to the left to cause the simultaneous bridging of two pairs of contacts 20; a spring 52 brings the parts back to their original position when the trigger is released. The bridging contacts 45 are mounted on a rod 54. Round the rod 54 are collars 62, 63 connected by a spring 64 and adapted to engage shoulders 60, 61 on the rod. A sleeve 65 surrounds the spring 64 so as to be in the path of movement of the collars 62, 63, and has an extension 66 connecting it to the trigger 47. When the trigger is pressed to the left, the bar 66 and sleeve 65 are moved in the same direction. This results (a) in a narrowed portion of the bar 66, Fig. 7, coming opposite a spring-pressed pawl 71 and allowing it to move so as to engage a groove 58 in the rod 54 and hold the rod against endwise movement and (b) in the movement to the left of the collar 62 and expansion of the spring 64. Towards the end of the movement of the trigger the shoulder 70 on the rod 66 engages the pawl 71, compelling this to release the rod 54 which moves under the action of the spring 64 to make contact. The action of opening the switch is similar, but in this case the pawl 71 extends across the end of the bars 54 instead of entering the groove 58. An insulated rod 18 holds the spring contacts 20 apart when the switch is open.

Title: Improvements in or relating to miners' lamps
IPC: F21L23/00
Filed: 1949-03-11
Abstract: 662,518. Igniting miners' lamps, KOEHLER MANUFACTURING CO. March 11, 1949 [Dec. 20, 1948]. No. 25423/49. Divided out of 662,468. Class 75(iii) In a miner's safety lamp wherein the spark ignition mechanism is operated by rotation of a shaft which extends through a passage in and projects from the fuel fount, the mechanism being movable to its operative position by sliding the shaft. the latter is resiliently urged so that the mechanism is normally held below the level of the wick, and air is prevented from passing between the passage and the shaft. The fount may be used in a lamp of the form described in Specification 662,468, An opening d, for the passage of sparks, is located in the side of a friction-wheel holder 25 mounted on the fount 2 and normally lies below the level of the wick. A hollow stem, projecting from the base of the holder 25 and carrying two spaced bosses 28, 29 passes into a tubular receiver 27, the ends of which are sealed to the top and bottom of the fount. A shaft 31, which operates the friction wheel by eccentric cam action. extends through the holder, stem and receiver, and terminates in a knob 33, a return spring 34 confined between a shoulder on the shaft and a restriction 36, formed in the receiver 27 to prevent air from passing into the lamp, normally maintaining the holder 25 against the fount 2. A flat provided on the boss 28 lies at a right angle to a flat on the boss 29, so that when the knob 33 is pushed upwards, the boss 28 slides through the correspondingly shaped hole 35 in the fount,. until the boss 29 engages the top of the fount, by which time the opening d of the holder 25 lies opposite the wick. Subsequent rotation of the knob 33 results firstly in rotation of the wheel a and loading of a spring, and secondly in release of the shaft 31 from the wheel a so that the latter is rotated rapidly to ignite the wick. To remove the igniter from the fount the latter is removed from the lamp, and the holder 25, after removal of the knob 33. is raised to free the boss 28 from the fount, and then rotated to bring the boss 29 into register with the hole 35. When the fount is in position on the lamp rotation of the shaft 31 to remove the igniter is prevented, since the flint-tube c which projects laterally from the holder 25 would strike the chimney of the lamp.
